Linux怎么查看线程

2023-06-28 09:11

关注

这篇文章给大家分享的是有关Linux怎么查看线程的内容。小编觉得挺实用的,因此分享给大家做个参考,一起跟随小编过来看看吧。

Linux系统的进程是由线程组成的,当然Linux进程下的线程数是不固定的,可以是一个进程,也可以是多个进程。

Linux怎么查看线程

pstree命令以树状图显示进程间的关系(display a tree of processes)。ps命令可以显示当前正在运行的那些进程的信息,但是对于它们之间的关系却显示得不够清晰。在Linux系统中,系统调用fork可以创建子进程,通过子shell也可以创建子进程,Linux系统中进程之间的关系天生就是一棵树,树的根就是进程PID为1的init进程。

1>.安装pstree命令行工具,包名为:“psmisc”

总结:

  通过pstree清晰的看到进程的父子关系,但是进程状态查看,还是需要ps、top等命令。pstree命令是用于查看进程树之间的关系,即哪个进程是父进程,哪个是子进程,可以清楚的看出来是谁创建了谁。

Linux怎么查看线程

三.直接去“/proc”对应PID的status目录查看

由于在Linux操作系统中,正在运行的程序都会在/proc这个目录下存放运行时文件的状态信息,因此我们在这个目录下,找到对应的进程ID就可以查看到该进程打开的线程数。当然还有一些其他的详细信息都在这个目录下存放着。
